Azapin 15 mg may interrupt the metabolism or activity of Carbamazepine, Phenytoin or Cimetidine. Patient should avoid Alcohol & Diazepam while taking Azapin 15 mg.

Mode Of Action

Pharmacodynamics: The mechanism of action of Azapin 15 mg as with other drugs effective in the treatment of major depressive disorder is unknown. Evidence gathered in preclinical studies suggests that Azapin 15 mg enhances central noradrenergic and serotonergic activity. These studies have shown that Azapin 15 mg acts as an antagonist at central presynaptic α2-adrenergic inhibitory autoreceptors and heteroreceptors, an action that is postulated to result in an increase in central noradrenergic and serotonergic activity. Azapin 15 mg is a potent antagonist of 5- HT2 and 5-HT3 receptors. Azapin 15 mg has no significant affinity for the 5-HT1A and 5-HT1B receptors. Azapin 15 mg is a potent antagonist of histamine (H1) receptors, a property that may explain its prominent sedative effects. Azapin 15 mg is a moderate peripheral α1-adrenergic antagonist, a property that may explain the occasional orthostatic hypotension reported in association with its use. Azapin 15 mg is a moderate antagonist at muscarinic receptors, a property that may explain the relatively low incidence of anticholinergic side effects associated with its use.Pharmacokinetics: After oral administration of Azapin 15 mg tablets, the active constituent Azapin 15 mg is rapidly and well-absorbed, reaching peak plasma levels after about 2 hours. Binding of Azapin 15 mg to plasma proteins is approximately 85%. The mean half-life of elimination is 20-40 hours; (26 hours in males, 37 hours in females). The half-life of elimination is sufficient to justify once-a-day dosing. Azapin 15 mg displays linear pharmacokinetics within the recommended dose range. Azapin 15 mg is extensively metabolized and eliminated via the urine and faeces four days. Major pathways of biotransformation are demethylation and oxidation followed by conjugation.


Pregnancy Category-C. Patients should be advised to notify their physician if they become pregnant or intend to become pregnant during Azapin 15 mg therapy. Patients should be advised to notify their physician if they are breastfeeding an infant.
